VENEER comma AND NAlLiNG MACHINE.

sPEoIFIcATIoIv forming part of Letters Patent No. 645,999, dated March27, 1900. Application filed July 3, 1899. Serial No. 722,688. (Nomodel.)

To all whom it may concern:

Beitknown that I, GEORGE A. GAGE, a citizen ofthe United States ofAmerica, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in VeneerCoiling and Nailing Machines, of which the following is a specification.

My invention relates to veneer-packageforming machines in which theveneering is wound upon a collapsible drum coacting with an outerpressure band and in which the overlapping parts of the veneering arefastened together by a traveling nailer coacting with said drum andband.

Prominent objectsof my invention are to provide improved means, first,for uniformly expanding and collapsing said drum and rendering samerigid when expanded second, for operating the pressure-band; third, foroperating the drum and'nailer in proper relation to each other, and,fourth, for feeding and guiding the veneering and hoops upon the drum.

The minor objects of different features of construction shown will beunderstood from the following description with reference to theaccompanying drawings, in which- Figure 1' is a front elevation of amachine constructed according to my invention. Fig. 2 is a top plan ofsame. Fig. 3 is a vertical section on the line A A of Fig. 1. Fig. 4 isa vertical longitudinal section of the drum. Fig. 5 is a horizontalsection of one of the arms supporting a segment of the drum and itsguide, taken on the line B B ofFig. 4. Fig. 6 is a vertical section ofthe nailer-casing, showing the plunger therein. Fig. 7 is a side view ofpart of same, showing the cam for raising the plunger. Fig. 8 is asection on the line C O of Fig. 2, showing the clutch for operating thesupporting-shaft of the drum. Fig. 9 is a perspective view of a piece ofnailingor fastening strip suitable for said nailer.

In the construction shown the shaft 1 is journaled. in the members 2 and3 of the frame at one end and is steadied by the hinged bearing-piece tat the other end. The collapsible drum, consisting of the segments 5 andsupporting parts, is mounted on the shaft 1. Said supporting partsconsist of the arms or guides 6, rigidly mounted on the shaft 1, and thearms 7, rigid on the segments 5,and each slidingly seated between a pairof the arms 6. The plates 8 are secured to the outside of the arms 7 andabut against the guides 6, thus holding the segments againstlongitudinal movement.

Springs 9'are secured to the guides 6 and to the segments 5 at each endand on each side of said guides. Said-springs urge the segments normallyinward or normally collapse the drum.

The arms 10 are provided with inclines 11, which coact with theoppositely-inclined ends of the arms 7 in urging the segments out wardlyor expanding the drum. The arms 10 are rigidly secured at one end to thesleeve 12, which has a sliding movement longitudinal of the shaft 1 andis secured thereto against relative rotation by means of the arms lOandguides 6. The sleeve 12 is moved on the shaft by means of the lever 13,which is pivoted to the frame at 14 and is pivoted at 15 to the collar16, which is seated in a groove in said sleeve 12 in such manner as topermit the revolution of the sleeve 12 and members 10 with the shaft 1.

The pulley 17 is loose on the shaft 1. A collar 18 is rigid on the shaft1 and connected with the pulley 17 by a clutch arranged to automaticallyrelease said collar and shaft from the pulley at the end of eachrevolution of the shaft.

The form of clutch shown consists of a slid ing bolt 19, seated in asuitable recess therefor in the collar and arranged to engage the hub ofthe pulley when forced into'the recess 20 in said hub. Said bolt has ashoulder 21 thereon, against which the spring 22 acts in normally urgingthe bolt into the recess 20.

pressed momentarily, the spring 25 acting to immediately return themember 24 to the proper position to cam with the shoulder 23. Thefoot-lever 27 is pivoted to the member 2 of the frame at 28.

The pulley 17 is connected, through the belt 29, with a maindriving-shaft. (Not shown.) Said driving-shaft also connects, throughthe belt 30, with the pulley 31 on the shaft 32, which is journaled inthe members 33 and 34 of the frame.

The pulley 35 on the shaft 32 connects, through the belt 36, with thepulley 37 on the shaft 38, which is journaled in the members 2 and 3 ofthe frame.

The shaft 38 has a clutch 39 feathered thereon and slidablelongitudinally of the shaft through the action of the lever 40. Thepulley 41 is loose on the shaft 38 and arranged to be engaged by theclutch 39 when same is thrown toward the pulley by the lever 40. Thepulley is provided with an inclined projection 42, which cams againstthe projection 43 on the lever for throwing the clutch out of engagementwith the pulley at the end of each revolution. The pulley 41 has fixedthereto at 104 a cable 44, which runs over the sheave 45 and attaches at46 to the arm 47 (see Fig. 3) of the nailer-frame and extends thenceover the sheave 48 and has secured thereto a weight 49.

The nailer-frame consists of the arms 47 and 50, rigidly securedtogether and slidingly mounted on the horizontal rods or guides 51. Themailer-casing 52 is rigidly secured to the arm 50. The shaft 53 isjournaled in the arms 47 and 50, has the clutch 54 feathered thereon,slidable longitudinally of the shaft, and carries the loose pulley 55.Said pulley 55 is connected, through the belt 56, with thedriving-shaft. (Not shown.) The spring 57 normally urges the clutch 54into engagement with the pulley 55. The shaft 53 has the cam 58 rigid onthe end of said shaft in the easing 52. Said casing carries a plunger59, which has ashoulder 6O resting upon said cam. The spring 101normally urges the plunger downward in the casing. At the lower end ofthe casing 52 is aslotted guide 61 for the nailing-strip, supported onthe casing by the arm 62. The plunger 59 carries a nailing-head 63,which is vertically adjustable by means of the set-screws 64. The arm orrod 65 is rigidly secured to the member 66 of the frame and has its freeend beveled to cam against the shoulder 67 of the clutch and throw sameout of engagement with the pulley 55. The pressure band or apron 68 issecured to the upper ends of the arms 69, which are arranged in twopairs and pivoted together and to the frame by means of the horizontalshaft 70. Arms 71 pivotally connect the lower ends of the arms 69 with ahorizontal rod 72. The spring 73 connects the lower ends of each pair ofarms 69 and normally draws same together, so as to raise the rod 72 andurge the upper ends of the arms 69 upwardly and inwardly, and thustighten the bands 68 against the drum. The lever 74 is pivoted at 75 tothe member 76 of the frame and rests upon the rod 72. The catch 77 issecured to the frame and serves to lock the lever 74 in the depressedposition.

The hoop-guides 78 are made in the form of a trough, open at each end,mounted on a cross-piece 79, and may be adjusted thereon longitudinallyof the cross-piece and secured by the set-screws 80. The guide 78at theright has its outer wall raised slightly at 81 to serve as a guide forthe main sheet of veneering. The wallat the left of each guide 78 isseparate from the bottom piece and has a rod 82 rigid thereon andpassing through a perforation in the opposite wall, where same issecured by a set-screw 83. The guides 78 may be widened by setting saidrods toward the left. The cross-piece 79 is rigid on the arms 84, whichare pivoted at 85 to the members 86 of the frame. At the upper ends ofthe members 86 are projections 87, serving as a stop for the arms 84.Each spring 88 is secured at its lower end to one of the members 86 andhas its upper end engaging one of the arms 84 and urging same normallyagainst the stops 87. Said springs are coiled around the pivots 102 andso arranged that the arms 84 may be swung down and away from thedrum ontheir pivotal connection at 86, carrying the guides 78 with same.

The nailing-strip shown is made of a sheetmetal strip 89, cut to formthe prongs 90. The member 4 is pivoted at 91 to the member 92 of theframe and is provided with a handle 93, whereby same is swung away fromthe shaft 1. One of the segments 5 has a shoulder 94 secured under itsedge, and the ad= joining segment is beveled at 95 to permit the edge ofthe veneering to be readily inserted against the shoulder 94. Prongs 103project slightly above said beveled segment and prevent slipping of theveneeriug. The presser-roll 96 is supported on arms 97, sliding in themembers 98 of the frame. The arms 97 are reduced and threaded at theirupper ends and provided with nuts resting upon the members 98 andlimiting the downward movement of said arms. The springs 99 encircle thereduced parts of the arms 97 and act against the shoulders 100 of saidarms to normally urge the pressure-roll downward upon the veneering.

The operation of my device is as follows: The pulley 17, shaft 38, andpulley 55 are constantly revolved through their connection with the maindriving-shaft. (Not shown.) The drum is expanded in the position shownby pulling the lever 13 toward the right, (see Figs. 1 and 2,) theinclines 11 urging the arms 7 of the segments 5 away from the shaft 1against the action of the springs 9. The lever 74 is released from thecatch 77, thus bringing the apron up against the drum. The operator thenfeeds a sheet of veneering upon the guides 78 and along the guide 81,inserting the edge of the veneering under the edge of one of thesegments and against the shoulder 94 of said segment. The lever 27 isthen depressed to release the bolt 19 of the clutch and cause same toengage the-pulley 17. This causes the shaft 1 to make a singlerevolution, the bolt being released through contact with the arm 24 atthe end of such revolution. The veneering has now been wound around thedrum, so that the ends overlap. The operator now moves the lever 40toward the right, causing the clutch 39 to engage the loose pulley 41and revolve same with the shaft 38. The pulley 41 makes a singlerevolution, winding the cable 44 around same and being released from theclutch by the action of the cam 42 against the projection 43 of thelever. This operates, through the cable 44, to move the nailer-frame 47,with the casing 52 and shaft 53, along the guides 51 toward the left ofFigs. 1 and 2. As soon as the shoulder 67 of the clutch 54 is releasedfrom the rod the clutch, engaging the revolving pulley 55, will revolvethe shaft 53, and thus operate the plunger 59 through the action of thecam 58 and spring 60. When the pulley 41 has been released from theclutch 39, the weight 49 will operate to move the nailer back toward theright until its clutch 54 is released from the pulley 55, when theplunger 59 will cease to operate. Before the nailer is started anailing-strip 89 is fed upon the guide 61 under the plunger. The plungerwill drive the. prongs through the overlapping part of the veneering andagainst the drum, the prongs bending slightly, so as to clench on theinside of the drum. The operator then depresses the lever 74 under thecatch 77 to loosen the pressure-band 68 and throws the lever 13 towardthe left to collapse the drum.

The member 4 is then swung toward the right, free from the shaft 1, andthe veneer-package is removed at that end. The guide81 serves to feedthe veneering in proper position on the drum. To form a hooped package,the hoops are fed through the guides 78 and the drum is caused to makean additional revolution to coil said hoops around the package. The arms84, with the guides 78, are then turned down away from the drum topermit the operator to nail the hoops.
